Car v Bicycle v Public Transport v Power Boat

I'm not a rev head but I do watch Top Gear from time to time, it's quite funny at times. Tonights programme had a race across London from Kew to City airport in the east. The bicycle came first, boat second, PT 3rd and car last. It's all a bit spoofy and to be honest the boat would have come first but for low speed limits for 2/3 of the course. Then again it would have come last if the speed limits had been in place for the whole trip
